1 SOFTWARE RELEASE DELIVERABLE
The Digivance CXD software upgrade process is based on packaging utilities built into the
Linux-based operating system used by Digivance CXD. The software upgrade is a set of
interdependent packages delivered in a self-extracting executable named so as to reflect the
revision of the contained software; for example: hr-2.1.0-upgrade would be used to upgrade a
target Hub or RAN CPU to version 2.1.0. When invoked, the upgrade executable will
automatically take the appropriate actions to upgrade the target CPU.
2 RELEASE NOTES
The release notes delivered with each software release distribution will contain specific details
about the changes being made in that software release. The release notes will itemize each
change made, including a description of the problem/issue being addressed, a description of
how the problem/issue was resolved, and the impact of the change on the NMS.
Included in the release notes are details of any upgrades to the FPGA images, including
revision number information contained in the latest release build. To ensure the latest
documentation matches the current packaged images, the release notes will be the only place
where this information is captured in external/customer documentation.
3 UPGRADING EXISTING SYSTEM
The most common upgrade scenario is one where an existing, fielded, operational system is
having all of its CPU’s upgraded to the next version of software. Some important notes
regarding this type of upgrade:
